17//! # Common pallet
18//!
19//! The Common pallet provides functionality for handling collections.
20//! 
21//! ## Overview
22//! 
23//! The Common pallet provides functions for:
24//! 
25//! - Setting and approving collection soponsor.
26//! - Get\set\delete allow list.
27//! - Get\set\delete collection properties.
28//! - Get\set\delete collection property permissions.
29//! - Get\set\delete token property permissions.
30//! - Get\set\delete collection administrators.
31//! - Checking access permissions.
32//! - Provides an interface for common collection operations for different collection types.
33//! - Provides dispatching for implementations of common collection operations, see [dispatch] module.
34//! - Provides functionality of collection into evm, see [erc] and [eth] module.
35//! 
36//! ### Terminology
37//! **Collection sponsor** - For the collection, you can set a sponsor, at whose expense it will 
38//! be possible to mint tokens.
39//! 
40//! **Allow list** - List of users who have the right to minting tokens.
41//! 
42//! **Collection properties** - Collection properties are simply key-value stores where various 
43//! metadata can be placed.
44//! 
45//! **Collection property permissions** - For each property in the collection can be set permission 
46//! to change, see [PropertyPermission].
47//! 
48//! **Permissions on token properties** - Similar to _permissions on collection properties_, 
49//! only restrictions apply to token properties.
50//! 
51//! **Collection administrator** - For a collection, you can set administrators who have the right 
52//! to most actions on the collection.
